摘要： System and method for assigning labels in a data transmission network (10) in which flows of data composed of packets (16) are transmitted from a source node to a destination node through a plurality of switching nodes and of the type wherein an identification label (18) identifying each flow of data is added by a transmitting node (12) to each packet of the flow of data before the packet is transmitted from the transmitting node to a receiving node (14) adjacent to the transmitting node, the identification label being recognized by the receiving node for the identification of the flow of data. Each switching node comprises identical label assignment means (20 or 22) for generating an identification label each time a new flow of data is received by the node, the label assignment means of the transmitting node and of the receiving node both generating an identical label when they both receive the flow of data, thereby avoiding the transmitting node (or the receiving node) from having to send the identification label to the receiving node (or the transmitting node) in order to be recognized by the receiving node when receiving the packets of said flow of data.

摘要： This invention deals with data communication networks and more particularly with a method and system for optimizing data link occupation in a multipriority data traffic environment by using data multiplexing techniques over fixed or variable length data packets being asynchronously transmitted. Said packets are split into segments including both a segment number and a packet number. Then the segments are dispatched, on priority basis, over available links or virtual channels based on a so-called global link availability control word indications, which control word is dynamically adjusted according to specific predefined conditions.

摘要： This adaptive bandwidth allocation for Non-Reserved traffic over high speed transmission links of a digital network is operated through regulation of data packet transfers over network nodes/ports including input/output adapters connected through a switching device.
To that end the network node is assigned with a Control Point computing devise (CP) storing a Topology Data Base keeping an image of the network.
This Data Base is periodically and at call set up updated by Topology Data Base Update messages (TDUs) including an Explicit Rate parameter for link l indicating the current available bandwidth on link l, and a parameter N NRl indicating the number of Non-Reserved connections on link l.
These informations are used within each Adapter to periodically regulate the transmission bandwidth assigned to each Non-Reserved traffic connection within the network. To that end, each adapter is provided with an Access Control Function device for each attached connection (data source) and a Connection Agent (CA) getting, on request, required current link informations from the attached Topology Data Base.

摘要： A communications system comprises a memory which is shared by a plurality of users, each one receiving and transmitting messages to each other. In the present system, a message is composed of a plurality of data buffers stored in the memory and each data buffer is controlled and mapped to a unique direct control block (DCB) which stores the characteristics of said data buffer. The chaining of the DCB forms the whole message which may be multicast to a plurality of users. Therefore, in order to improve the performance of such communications system, one may duplicate the message as many times as necessary without re-writing the data in the personal storage of each user by using an indirect control block (ICB) which represents the message duplicated. Each ICB stores the characteristics of the message duplicated and points to a DCB. A field in the DCB enables to count the number of duplication of the message. The DCB and ICB stores different fields which are required in order to perform the operations of lease control block from the free queues, the operations of message enqueue in the user queue, the operations of message dequeue from the user queue, and the operations of message release to the free queues. Two separate free queues FDCBQ and FICBQ chaining the free DCB and ICB are provided and are controlled by two control blocks FDQCB and FIQCB.
The present apparatus and method may also be used for multicasting data buffer which composes a message by adding new fields in the ICB. In this case, the message to be multicast may have a content different from the original one, which requires therefore that to each ICB correspond a unique DCB.
